Separate the VM page table backend operations from the state machine since
the amdgpu_vm.c file is becoming to complex.
The allocating, freeing and updating page tables and page directories can
easily be moved into a separate file.
While at it cleanup everything checkpatch.pl reported and rename the
functions a bit to make more clear that they belong together.
